Dodecahedron learning
Thu, Nov 15, 2007
Have you ever wondered how to model a Dodecahedron D12? How about generating a flat pattern of this 3D geometric wonder? Recently at a technical education conference my employer CADDWorks Corp. received a request by a high-school teacher for information on this very topic. In this video you will see some basics of surface modeling, linked dimensions, and flattening sheet-metal boxes. Enjoy, and continue to send your suggestions to tim(at)solidworker.com.
(edit) After making the first revision of this video I started thinking about other ways to create the D12 shape. I have now added a second method for creationg a D12 that is not based on surface features but rather solid features.

You go dodecahedron! Very impressive Tim, thank you. I learned loads from these two videos.

Hey there, i´m having a problem watching your video, around minute 18 the video goes black and I can´t see how you do the shell feature. I don´t know if it´s about the link or my computer… Thank you.

There is a much easier way to do it. One extrusion with taper, a mirrored solid, a rotation of the mirrored body and an intersection.

Gooood, Mental exercise! Want more with at least this level of complexity.
Thank you.

If the goal is a sheet metal part of the dodecahedron, quickest way to make it is:
1. Starting with Sheet metal Base Flange in a shape of the Flat Pattern. The required outline is obvious in that case and utilizing patterning tools of the Sketcher makes the task quite simple. It is required the theoretical outline to be shrunk all around for the value of relief though (Offset command) and corner reliefs added .
2. The second feature of the part will be Sketched Bend.
Only two features, the same result.
